The 290L HD detect high and extra high voltage in AC lines. Elongated insulation rods permit checking hightension circuits from a safe working distance. The handy telescopic rods make these detectors compact, lightweight, and easy to use.
● Telescopic, compact, lightweight.
● Self test button feature.
● Easy to recognize indication.
● High intensity red LED and intermittent audible alarm for easy recognition in full sunlight and noisy environments.
● Water proof (detecting head impervious to water).
